本研究法用γ线吸收法，测量了８７例６０岁以上正常老年人的骨密度，以观察中度高原地区老年人骨密度的变化规律，结果提示：中度高原地区骨密庆变化趋势与平原地区一样，密度与年龄成反比，女性骨量比男性丢失快且早，７０岁以上男女之间差别缩小，７０岁以下组平原地区测定值与高原存在显著差异（Ｐ＜０．００１），造成差异的原因我们认为与高原地区紫外线强，食物及人接受的照射剂量比平原高，继而摄取及皮肤转化钙调节类激素增多，骨重建增强所致。
In this study, the bone density of 87 elderly people over the age of 60 was measured by γ-ray absorption method to observe the changes of bone mineral density in the elderly in moderate plateau. The results showed that: In plain areas, the density is inversely proportional to age. Female bone loss is faster and earlier than men, and the difference between men and women over 70 years of age is narrowed. There is a significant difference (P <0.001) between the measured values in plain areas under 70 years of age and the plateau, The reason for the difference We believe that the higher the UV light in the plateau area, the higher dose of food and human exposure to radiation than the plain, followed by uptake and conversion of calcium-regulated skin hormones, increased bone remodeling.
